LGE · Fast Recovery / High Efficiency Diodes · DO-41
HER108G from LGE, in a DO-41. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode, marked by the color band on the molded DO-41 body; blocks up to 1000 V DC (VRRM 1000 V for HER108G). |
| 2 | A | passive | Anode, the lead opposite the color band; carries 1.0 A average forward current at TA = 55 °C with VF of 1.7 V max at 1.0 A for HER108G. |
